VX Series Floor Scale EN-1

1. INTRODUCTION This manual contains installation, operation and maintenance instructions for the VX Series Floor Scale.

1.1. SAFETY PRECAUTIONS

Please follow these safety precautions:

• Never operate in hazardous areas.

• The VX Series platforms may be used in dry environments only.

• The foundation at the installation site must be capable of safely supporting the weight of the floor scale

plus the weight of the maximum load.

• Ensure that vibrations near the installation site are kept to a minimum. This applies also when the floor

scale is integrated into conveying systems.

2. INSTALLATION

CAUTION: THE FLOOR SCALE PLATFORM IS VERY HEAVY. ALWAYS USE APPROPRIATE HOISTING

EQUIPMENT TO LIFT IT FROM THE PACKAGING AND TO MOVE IT INTO THE REQUIRED POSITION.

2.1. Unpacking 1. Remove the outer packing materials from the top and sides of the Floor Scale.

2. Carefully lift the Floor Scale from the packing material, see caution notice above.

3. Available hoisting methods include the use of eye bolts and chains (not included). 10,000 lb models have two threaded holes on the top surface that will accept 3/4”-10 eye bolts. Lower capacity models have unthreaded holes at 3 locations, two 11/16” holes on the front panel and one 5/8” hole on the back panel. The use of eye bolts on the unthreaded holes will require the addition of matching nuts placed behind the panels. See figures 1a and 1b.

Figure 1a. Optional hoisting method 10000 lb models. Figure 1b. Optional hoisting method 5,000 lb and lower capacity models

EN-2 VX Series Floor Scale

2.2. Foot Adjustment 1. The four feet must be adjusted out of the shipping position and into the operating position. Use a 1-3/8” wrench to loosen

each foot and extend them to 4-1/2” (114mm) measured from the top surface of the platform.

2. At this position use a 1/2” wrench to rotate the jam nuts until they lock against the load cell. See figures 1c and 1d.

Figure 1c. Load Cell Foot in shipping position. Figure 1d. Load Cell Foot in nominal operating position.

2.3. Positioning 1. Ensure the surface is flat in the area where the scale will be positioned, especially in the region of the load cell feet.

2. If an Indicator is included with the floor scale, ensure that it is kept with the floor scale during positioning as there may be an attached connecting cable.

3. Position and lower the scale on to the final work area.

4. If floor plates or ramps are to be installed, these must be installed before final set up.

5. Check that the floor scale is level and check that all 4 feet are in full contact with the floor, use an external level on the top surface. If an adjustment is needed, first loosen the 1/2” jam nut near the top of the foot and rotate the bottom section of the foot. After adjusting, retighten the jam nuts. Recheck that all 4 feet are still in full contact with the floor.

6. Do not adjust the feet fully inward as this could cause interference with the top surface and result in weighing errors.

7. Ensure that the floor scale’s output cable does not become trapped or crushed during lifting or positioning.

2.4. Foot Plates Foot Plates (included) may be mounted around the feet to help prevent movement of the platform. Installation of the Foot Plates must

be done before final placement of the scale (refer to the section 5.4 for Foot Plate installation).

2.5. Cable Installation If the Floor Scale system was received with a pre-attached cable connected between the platform and Indicator components this

section can be skipped over. If the components were purchased separately or if a cable was not attached to either component follow

the steps below to make the proper cable connections.

Risk of Electrical Shock Disconnect all power sources before making cable connections to the Floor Scale platform or Indicator. Cable Connections should only be made by authorized and qualified personnel, such as an Electrical Technician.

VX Series Floor Scale EN-3

Connecting the Platform Cable

1. Remove the two fasteners on the junction box access cover located on the side panel of the platform.

2. Slide the junction box forward and out of the compartment. Remove the plastic top cover from the junction box.

3. Loosen the water-tight gland that does not have a cable inserted. Insert about 6” (150mm) of the cable through the gland

and into the junction box.

4. At the junction box end strip the outer jacket of the cable 1.5” (40mm) then strip 0.25” (6mm) from each single wire end.

5. On the cable determine which wire connects to the cable’s shielding. This is normally a Bare wire. Optionally the shield

may be twisted into a pig-tail. This shield connection must always be connected to the point marked “SHIELD” or “GND”.*

6. Connect the wire ends to the “INPUT” terminal block inside the junction box, see Figure 2. The Shield wire must be

connected to the connection marked “SHIELD”. The remaining wire colors may be connected to the terminal block in any

arrangement though a recommended color chart is shown below in Table 1. If a label is attached to the cable follow the

color code listed on the label instead.

7. After making all connections make a record of the wire color to signal names. This information will be needed when

connecting the Indicator to the other end of the cable.

8. Route the other end of the cable into the platform’s junction box compartment and pass it out through the rear opening.

9. Reinstall the plastic top to the junction box, tighten the water-tight gland around the cable, return the junction box to the

internal compartment, reinstall the external cover and fasteners.

10. Route the cable out from under the platform to the location where the Indicator will be mounted. Ensure that the cable will

be protected against possible damage when routed to the Indicator.

11. The cable near the platform must lie free without tension. Excessive tension may result in weighing errors.

*Note: The standard cable included with the VX Floor Scale will have either a Bare wire or a Yellow wire connected to the Shield. On

some cable assemblies a label may be attached listing the Shield wire and the recommended wire color connections.

EN-4 VX Series Floor Scale

Connecting the Indicator Cable

1. Route the cable from the platform to the location where the Indicator will be mounted.

2. The cable near the platform must lie free without tension. Excessive tension may result in weighing errors.

3. Ensure that the cable will be protected against possible damage when routed to the Indicator.

4. Consult the installation instructions of the Indicator to properly connect the cable wires to the Indicator.

5. Use the recorded wire color information from the platform connections to make the proper wire connections.

2.6. Legal for Trade Sealing

If required the junction box may be sealed as shown in Figure 3. The junction box is accessed by removing the cover plate on

the FRONT side panel of the platform.

Consult the instructions of the Indicator to properly seal the Indicator component for Legal for Trade applications.

4. MAINTENANCE 4.1. Daily Checks • Check that the feet are properly seated in the holes of each load cell.

• Check that the 4 feet are in full contact with the floor.

• Check that the scale is free from debris, especially under and around the edges of the scale.

• Check that there is no damage to the connecting cable.

4.2. Cleaning

Risk of Electrical Shock Disconnect the power source before cleaning the scale with any liquids.

Exterior maintenance of the floor scale is limited to regular cleaning.

- Wipe surfaces with a damp cloth.

- Use only common household cleaning agents.
